ous kinds of hay produced in Michigan, as follows: 

 Clover, 27; timothy, 26; clover and timothy mixed, 

 35 ; alfalfa, G ; millet, 2 ; other tame grasses, 1 ; grains 

 cut green, 1; wild hay, 2. There has undoubtedly 

 been an increased yield of alfalfa in the interval 

 and, in the opinion of the statistician of the Bureau 

 of Crop Estimates, it may now amount to 8 or 10 

 per cent. Chippewa County in the eastern Upper 

 Peninsula has for years been a leading commercial 

 producer of hay, and its yield in 1921 was 52,210 

 tons. The largest producers of hay, however, are 

 such well-developed agricultural counties in the 

 Lower Peninsula as Gratiot, Sanilac, and St. Clair, 

 each yielding more than 100,000 tons. One occa-

 vetch, sweet clover and other forage crops not regu-

 such imported species as lupine, serradella, spurry-

 cost of production, habit and the belief that this 

 crop was a prerequisite to successful seeding of hay 

 caused farmers annually to set aside a portion of their 

 tilled land for wheat. It has been the staple crop 

 chiefly of the southern section, and the Thirteenth 

 Census showed few counties whose wheat production
